Primary application for these bearings is as guide rollers, for the telescopic mast sections in forklifts and related machines.
The bores of mast guide bearings are fitted, as with any standard industrial bearing. Unlike typical industrial bearings however, the outer diameter of a mast guide bearing acts directly against a steel mast rail.
Depending upon the design of the mast and fork carriage assembly, mast guide bearings can be subject to very high radial and thrust loads, as well as high intermittent shock loads.
Mast guide bearings are intended for low speed, high load applications. The seals are very tight fitting. The grease fill is very high, typically over 90%. The internal design (ball and roller complements) maximizes the load capacity.
